Transit-guru: My Life in the bus lane

Curitiba’s Bus Rapid Transit system is one of the most admired public transportation systems on the planet, garnering accolades and spawning spin-off systems in cities like Bogotá and Los Angeles.
Curitiba’s six dedicated fast-lane bus lines traverse the city, carrying 36,000 passengers per hour and 2.3 million overall every day. It’s affordable too — a single fare costs $1.25 and will take you 20 kilometers outside downtown.
